Vacuolar protein sorting-associated protein 26; Component of the retromer complex which acts in conjunction with wingless (wg) and clathrin-mediated endocytosis to sustain a wntless (wls) traffic loop. This loop encompasses the Golgi, the cell surface, an endocytic compartment and a retrograde route leading back to the Golgi, thereby enabling wls to direct wg secretion. The hh and dpp signaling pathways do not require the retromer complex suggesting that it does not play a general role in exocytosis. Belongs to the VPS26 family.

ADP-ribosylation factor-like protein 1; GTP-binding protein involved in protein trafficking; may modulate vesicle budding and uncoating within the Golgi apparatus.

Protein spire; Acts as an actin nucleation factor, remains associated with the slow-growing pointed end of the new filament. Promotes dissociation of capu from the barbed end of actin filaments. Involved in intracellular vesicle transport along actin fibers, providing a novel link between actin cytoskeleton dynamics and intracellular transport. Required for localization of determinants within the developing oocyte to the posterior pole and to the dorsal anterior corner. Links Rho family signaling and Jnk function to the actin cytoskeleton.

Guanine nucleotide exchange factor subunit Rich; Probable component of a guanine nucleotide exchange factor (GEF) that may be required for efficient fusion of endosome-derived vesicles with the Golgi (By similarity). Plays a role in regulating Rab6-dependent CadN transport in photoreceptor cells which is required for the formation of normal synaptic connections between axons from the inner photoreceptor cells in the eye and postsynaptic cells in the brain medulla layer M6, and for the generation of normal postsynaptic responses.

ADP-ribosylation factor related protein 1; GTP binding. It is involved in the biological process described with: protein localization to organelle; Golgi to plasma membrane protein transport; intracellular protein transport.

Secretory 71; Small GTPase binding; ARF guanyl-nucleotide exchange factor activity; guanyl-nucleotide exchange factor activity. It is involved in the biological process described with: positive regulation of neuron remodeling; positive regulation of endocytosis; Golgi to plasma membrane protein transport; regulation of ARF protein signal transduction.

Cappuccino (capu) encodes a formin family protein that nucleates actin filaments and accelerates their elongation. It works with the product of spir to build an actin mesh that fills the oocyte during mid-oogenesis. capu is necessary for polarity establishment and female fertility.

Gartenzwerg, isoform B; Gartenzwerg (garz) encodes a guanine nucleotide exchange factor localized to the cis-Golgi apparatus. The roles of the product of garz include membrane and protein trafficking between the Golgi apparatus and the endoplasmic reticulum. It is required for epithelial morphogenesis in the embryo.

Monensin sensitivity 1 (Mon1) encodes a protein that forms a complex with the product of Ccz1 and acts as an exchange factor of the small G-protein encoded by Rab7. It activates and recruits the product of Rab7 to the maturing endosome, inducing the fusion of the matured endosome with the lysosome. Mon1/Ccz1 complex loss of function results in Rab7 phenotypes.
